000012293 520__ $$2eng$$aIncremental dynamic analysis (IDA) is an effective and precise procedure to carry out seismic risk assessment to investigate expected structural responses, seismic vulnerability and financial loss to various types of structures. The illustrated example is a rigid frame reinforced concrete bridge as a key railway pivot designed to the draft code for seismic design of railway engineering. A quantitative risk analysis procedure is conducted, including selecting a suitable suite of site-dependent ground motions, performing IDA on a nonlinear model of the prototype structure, organizing and parameterizing the IDA results into different damage states in a probabilistic format. The financial risk assessment can be estimated to predict direct financial loss in dollars and help to select a reasonable method of repair that can restore the specific functionality and easily be comprehended by either engineers or facilities owners. This paper extends a probabilistic risk assessment methodology to quantify expected annual financial loss for the rigid frame reinforced concrete bridge, correlating the systematic seismic capacity and demand to financial risk. The result shows that the railway bridge designed to design basic earthquake may face up to more financial loss statistically than the loss caused by maximum considered earthquake events for the occurrence probability of the latter is too lower in the local region. The result suggests that facility owners and managers may reduce the seismic financial risk with selecting proper retrofit strategies against the minor and moderate earthquakes with a relative low collapse probability.
